karan39 facing the same issue on my 2a+. The basic purpose of a phone is to make calls, but with this phone sometimes I am made to wait 30 seconds to 2 minutes just so that the signals are back to make a call! Mostly when the phone is not in use the signal goes off. Once you are on the phone screen the signals are intact even though it keeps on fluctuating between 5g and 4g. The internet speed is another issue.
Previously I’d used LG G8X with 4g max capabilities and yet it out performs the 2a+ in all aspects of connectivity, be it internet speed of signals.
I have started to lose hope that Nothing would fix it. Eagerly waited for a couple of updates but they never really settled these bugs or ‘intended inconveniences’. Switch to Nothing, or atleast 2a+ was a big mistake. A victim of hype and PR. 😭
